the mounting rod 2 is pushed to enable the round cover 3 to move upwards so that the wiping plate 5 and the scraping plate 6 are not blocked by the round cover 3 any more, the ball sliding block 12 on the mounting plate 11 still slides in the vertical groove 22 on the mounting rod 2 when the mounting rod 2 moves upwards in the cylinder 1, and then the mounting rod 2 and the mounting plate 11 do not rotate relatively under the state, because the vertical rod 52 slides on the mounting plate 11 axially, and further the vertical rod 52 cannot rotate around the mounting plate 11 when the mounting plate 11 does not rotate, at the moment, the disc 4 on the mounting rod 2 only approaches to the rolling ball 45 in the vertical direction, at the moment, the mounting plate 11 does not rotate relatively with the disc 4, and the spiral chute 41 on the disc 4 is over against the rolling ball 45, and finally the disc 4 moving upwards can contact with the rolling ball 45 and enable the rolling ball 45 to enter the spiral chute 41;
after the rolling ball 45 enters the spiral chute 41, the mounting rod 2 is continuously pushed to enable the disc 4 to move upwards, at the moment, the disc 4 moving upwards transmits force upwards through the rolling ball 45, the elastic force of the second spring 571 is smaller than that of the first spring 53, at the moment, the second spring 571 is firstly compressed, then the piston rod 58 slides to enter the piston cylinder 57, at the moment, air in the piston cylinder 57 is discharged through the hard pipeline 62, the second spring 571 is compressed to the extent that the upward moving force of the disc 4 when the second spring 571 cannot be compressed again is transmitted to the first spring 53, at the moment, the first spring 53 is compressed, then the vertical rod 52 moves upwards, and further the vertical rod 52 moving upwards drives the inclined rod 51 to rotate to enable the wiping plate 5 to move in the direction away from the axis of the cylinder 1, so that the wiping plate 5 can contact with the cervix, because the vertical groove 22 is connected with the spiral groove 21, the ball sliding block 12 already slides into the spiral groove 21 when the first spring 53 is compressed, at the moment, the mounting rod 2 and the cylinder 1 are controlled by hands not to rotate relatively, so that the mounting plate 11 can rotate when the mounting rod 2 continues to move axially relative to the mounting plate 11, and the rotating mounting plate 11 can drive the wiping plate 5 to rotate around the mounting plate 11 and scrape the inner wall of the cervix, so that secretions on the cervix are scraped off, and other substances can be avoided during sampling;
as shown in fig. 6, when the mounting plate 11 rotates, the vertical rod 52 axially sliding on the mounting plate 11 revolves around the mounting plate 11 as a center of a circle, and at this time, the rolling ball 45 rolls in the spiral chute 41, and then the rolling ball 45 rolls along a track of the spiral chute 41, and simultaneously, the rolling ball 45 gradually moves towards the center of a circle of the disc 4 along the track of the spiral chute 41 when rolling in the spiral chute 41, because the reset rod 43 is slidably connected to the bottom of the third retaining ring 59 through the limit block 44, and the chute direction formed on the third retaining ring 59 and matched with the limit block 44 vertically points to the center of a circle of the disc 4, and further, when the rolling ball 45 at the bottom of the reset rod 43 rolls in the spiral chute 41, the limit block 44 can relatively slide relative to the third retaining ring 59, so that the connection between the reset rod 43 and the third retaining ring 59 cannot be bent;
as shown in fig. 7, since the spiral chute 41 is connected with the spiral through groove 42, and the rolling ball 45 finally enters the spiral through groove 42 after sliding along the spiral chute 41, at this time, the vertical rod 52 moves downward under the action of the first spring 53, and the vertical rod 52 moving downward pulls the scraping plate 5 back to the original position through the inclined rod 51, the length of the spiral chute 41 is sufficient to enable the scraping plate 5 to rotate a circle around the axis of the mounting plate 11 to scrape a circle of the inner wall of the cervix;
when the wiping plate 5 moves in a direction away from the axis of the mounting plate 11, the wiping plate 5 drives the first circular plate 761 to slide outwards from the mounting cylinder 7 through the first L-shaped rod 76, because the first circular plate 761 and the second circular plate 79 are both attached to the inner wall of the mounting cylinder 7, and the air inlet pipe 77 is located between the first circular plate 761 and the second circular plate 79, and further when the first circular plate 761 is drawn out from the mounting cylinder 7, external air enters the mounting cylinder 7 through the air inlet pipe 77, and when the reset rod 43 slides into the spiral through groove 42, the vertical rod 52 descends to pull the wiping plate 5 back, the wiping plate 5 drives the first circular plate 761 to slide towards the mounting cylinder 7 through the first L-shaped rod 76, and because the air inlet pipe 77 is provided with the one-way valve 771, air in the mounting cylinder 7 cannot be discharged from the air inlet pipe 77, and further, the first circular plate 761 moving into the mounting cylinder 7 pushes the sealed air in the mounting cylinder 7 to push the second circular plate 79 to slide outwards from the mounting cylinder 7, the second circular plate 79 drives the scraper 6 to move in the direction far away from the axis of the mounting plate 11 through the second L-shaped rod 78, so that the scraper 6 can contact the inner wall of the cervix, and the mounting plate 11 in a rotating state drives the scraper 6 to move around the mounting plate 11 to scrape off epidermal cells on the inner wall of the cervix;
the disc 4 continues to move upwards to enable the magnet 46 fixedly connected to the disc 4 to gradually approach the metal plate 74, so that the vertical height between the magnet 46 and the metal plate 74 is smaller and smaller, because the mounting plate 11 is still in a rotating state, and then the blocking rod 72 axially sliding on the mounting plate 11 moves along with the mounting plate 11, so that the metal plate 74 finally enters the adsorption range of the magnet 46, at this time, the magnet 46 attracts the metal plate 74, and then the metal plate 74 moves downwards to approach the magnet 46 against the pulling force of the tension spring 75, the blocking rod 72 fixedly connected to the metal plate 74 and the metal plate 74 move downwards synchronously, and then the blocking rod 72 is pulled out from the mounting cylinder 7, at this time, the second disc 79 moves towards the annular stop 791 under the action of the third spring 781 and stops moving until contacting the annular stop 791, at this time, the air in the mounting cylinder 7 can be discharged through the insertion hole of the blocking rod 72 inserted in the mounting cylinder 7, further, positive pressure cannot exist in the installation cylinder 7, and the scraper 6 can be retracted to the original position at the moment;
when the blocking rod 72 is completely pulled out of the mounting cylinder 7, the pressing ring 73 on the blocking rod 72 contacts the air bag 731 and presses the air bag 731 after the scraper 6 returns to the original position, so that the normal saline in the air bag 731 is sprayed out to the position on the scraper 6 where the sample is just scraped through the spray pipe 732, and the sample scraped by the scraper 6 under the flushing of the normal saline flows into the receiving box 61 together with the normal saline;
the pressing ring 73 on the blocking rod 72 contacts the air bag 731 and continues to move downwards after being pressed, because the hard pipe 62 is arranged at the lower part of the metal plate 74, and then the metal plate 74 can contact the hard pipe 62 and apply pressure to the hard pipe 62 when continuing to move downwards, the magnet 46 has enough suction to the metal plate 74, and then the metal plate 74 at the bottom of the blocking rod 72 can apply larger pressure to the hard pipe 62, and then the force is transmitted to the piston cylinder 57 and the mounting plate 11, the hard pipe 62 is connected with the mounting plate 11 firmly enough, and the folding rod 55 arranged at the upper part of the piston cylinder 57 can not bear the pressure from the metal plate 74 and break, and then the piston cylinder 57 can be separated from the connecting state with the vertical rod 52 and fall at the upper part of the disc 4, and then the piston cylinder 57 can not follow the vertical rod 52 after being separated from the vertical rod 52, and then the second spring 571 can not bear the pressure of the first spring 53 any more, at this time, the second spring 571 is expanded to enable the piston rod 58 to slide towards the outside of the piston cylinder 57, and then the piston cylinder 57 can extract the physiological saline referencing the sample in the receiving box 61 through the hard pipeline 62;
the depth of relative sliding with the cylinder 1 can be observed through setting up the scale on the installation rod 2, after reaching gliding distance, the device is wholly taken out, then the round cover 3 is separated from the installation rod 2, at the moment, the installation rod 2 can be taken out from the cylinder 1 together with the disc 4, and then the piston cylinder 57 falling on the upper part of the disc 4 can be taken out, and the sample is directly subjected to slide microscopic observation by extracting the physiological saline participating in the sample, so that time and labor are saved.
